Protector: A Billionaire Step-Brother Romance

“Is—is that a problem?” I asked anxiously. He kissed me again.

“Oh sweetheart, no. I just want this to be everything you’ve ever dreamed it would be. I’m gonna make you feel so fucking good,” he promised, moving down to suck deep, tingling kisses into my inner thighs. I bucked my hips, desperate for him to touch me between my legs. After an agonizing minute of teasing, he pulled my panties to one side and lightly kissed my clit, with just enough pressure to make me cry out.

“Cole, oh my god,” I uttered. His tongue made a long, slow, lingering path down the length of my pussy, then flicked its way back upward to suck gently on my clit. I whimpered and instinctively tangled my fingers in his hair, pushing him deeper between my legs. He moaned happily, sending tickling vibrations down my legs. For what must have been several minutes he did the same dance over and over, pausing now and then to smile up at me. Finally, I felt something simultaneously fiery and cold, sharp and soft, totally fantastic rising up in me. My breath caught in my throat—just at that moment Cole reached one hand up to fondle my breast, rubbing circles around my nipple.

“Oh—oh god,” I murmured, closing my eyes tightly. I was moving my hips rhythmically now, to match Cole’s tongue between my legs. Just when I thought I might black out, a wave of overwhelming pleasure ripped through my body, coursing down my legs and arms, causing me to exclaim brokenly, “Cole!”

He didn’t stop, sucking and nibbling at my clit and massaging himself through his boxers, groaning all the while, until I came again and again. I shook uncontrollably, grasping at the sheets, mumbling his name under my breath like a prayer. He stood up quickly, pulled down his boxers to stand totally, beautifully naked in front of me, stroking himself. As soon as I regained control of my limbs I sat up and crawled forward to take his cock in my hand with a tentative curiosity. I had made out with guys before, and one had even seen me topless, but I had never touched a penis before. It was velvety smooth and long—much bigger than I’d ever anticipated, so big that it scared me to imagine how it could possibly fit inside me. I lightly rubbed a circle around the head of his cock, then leaned forward to take it slowly, carefully into my mouth.

Cole inhaled sharply and combed his fingers gently through my hair as I began to bob up and down the length of his erection. I took a quick look up at him and saw him with his eyes closed, biting his lip with a look of complete ecstasy on his face. The image was hot enough on its own to make me want him that much more, and I sucked his cock down as close to the back of my throat as I could before I felt like I might choke. He pulled me back and kissed me, hard, then flipped me back onto the bed to slide two fingers into my dripping pussy.

“Ohhh fuck,” I whispered, quivering at the sensation. I had never had anything inside me before—not my vibrator, not even my own fingers. It was intoxicating, and I wanted more, so much more. I moved against his hand, groaning. Just before I could come again, he withdrew his fingers and sucked them dry with a wry smile. I couldn’t help but make a pitiful whining noise. “I need you—I need you inside me, please, Cole!” I gasped.

“Are you sure?” he asked in an undertone.

“God yes,” I answered. He grinned widely and kissed me, pressing the tip of his cock teasingly at the opening of my pussy, making tiny, maddening circles there. I bucked my hips and pushed my tongue into his mouth, desperate for him to move this along. He toyed with me only a few moments more—and then sheathed his cock inside me with a throaty cry.

The sensation was unbelievable, unforeseeable. I yelped, and he caught it with another kiss as he started to thrust gently at first, then harder and deeper. He sucked my nipple into his mouth as he fucked me faster, driving himself deeper inside with each motion of his hips. I needed him to fill me up, to totally fill me, and again I wrapped my legs around his waist, feeling his muscles ripple against my body. He breathed heavily, licking and kissing my nipples and fucking me with short, rapid thrusts until I felt myself on the edge of coming again.

“It feels so good,” I mumbled, half-delirious. “So fucking good.”

“Yeah, baby? You want more?” he teased, through he looked as though he was almost ready to burst, as well. He swallowed and leaned back to tug me closer with one arm, like I weighed nothing at all, and lifted my leg up over his shoulder. He slammed into me harder, the full, throbbing length of his cock deep inside me, hitting a sweet, indescribable spot again and again until I began to shriek, unable to control myself.

“Oh god!”

“Tell me you want it,” he ordered calmly.

“I want it! I want you! God, Cole, you’re gonna make me come!”

He fucked me faster and faster still, rubbing my clit with his thumb. Totally overwhelmed, I could feel tears of pleasure welling in my eyes. I had never felt like this before.

“I wanna make you feel so good, Mackenzie,” he said, his voice so warm and so sincere it caused the tears to finally streak down my cheeks into my hair. “I wanna make you so happy.”

“Ohhhh—ahhh, Cole!” I exclaimed as the orgasm shuddered up my body. I felt my pussy clenching around his cock, so wet and hot, and he moaned, losing himself for a moment.

Then he opened his eyes and looked straight at me as he came. “Fuck!” he shouted, his massive cock shooting hot liquid deep into m

y pussy. He continued to thrust several times until, to my utter surprise, another orgasm shook me and I groaned his name. Then he withdrew and collapsed nearly on top of me, both of us breathing hard.

We lay there in silence for several minutes, just shuddering through the aftershock, inhaling each other, soaking in the moment. Then I felt him gingerly kiss my shoulder. I looked over at him and took in his image: sweat-soaked dark hair sticking up in tufts around his head, his gorgeous green eyes serene, full of adoration, and his lips curved in a beatific smile. Something came over me and I reached to take his hand in mine.

Finally, I broke the silence.

“So,” I said softly, “I’ve decided that I am going to stay with you, after all.”

Cole

The next morning was surreal. I woke up feeling as if I hadn’t even drifted off to sleep, I had felt so relaxed the night before. I moved my hand and found it still caressing the unbelievably gorgeous woman I’d made love with the night before—Mackenzie, the woman I’d sworn to protect. She was everything I knew she would be, every bit as warm and loving and eager as I knew she would be.

And she was my own step-sister.

Even as the smaller figure I held in my arms under my sheets snuggled closer to me, making a happy murmur in her sleep, the reality of what we’d just done hung over me like a pall. We were step-siblings, and we’d just spent the night in passion together, her beautiful naked body grinding against my toned form, my hardened cock pulsing deep inside her as she screamed my name, a name she was supposed to think of as only family. And yet here we were, my step-sister holding my larger hand against her bare nipple, and my cock resting on her ass, having let the entirety of my load spew into her last night.

I'd never done that before. Had sex with a woman without a condom, without any birth control. I'd always been safe, even when I was reckless as shit.

I reached down and massaged my member, remembering how it had felt. I’d been with so many women, living on my own in this apartment, in this very bed, but despite the pang of shame I felt trying to claw at the back of my mind, I couldn’t help but admit that the release of tension I felt when I let myself roll into an orgasm with my cock deep inside my step-sister was unlike anything I’d felt in…well, ever. Our bodies had moved like we’d known each other for years, like we were meant for this. I smiled at how stupid I sounded to myself, and I leaned over to kiss Mackenzie awake.

Her mouth curled into a little smile before she opened her eyes, and I knew she’d already been awake. A sleepy eye turned to look up at me affectionately, and she met me for a kiss on the lips, a slender hand reaching up to stroke my chest as we did. I felt her body, warm and secure, against mine as it moved with the slow, steady breathing of my broad chest. So maybe we did have to come to terms with the fact that we’d just spent the night fucking when we should have been getting to know each other as brother and sister—so what? This felt right. And above all, I’d taken a huge step in doing what I’d set out to do—to protect Mackenzie.
